I've been on Entocort 3 months now with hardly no side effects except for some general fatigue , in all its been working really well. I usually go to bed at around 1:30 am and wake up at around 9:30-10:00 am. That has always been my usual routine. In the last few months I went out to a night club 3 times in total. Obviously, I do not drink anymore so I pretty much keep myself hydrated through the night by drinking a lot of water. I came home last night and went to bed at 4:00 am feeling just fine, this morning I woke up at 11:00 am with a splitting headache feeling very sick. To sum up I felt like I drank a dozen beers the night before when really I just drank water. I felt like I had a HUGE hangover, thats the best way to describe it. This has hapened to me everytime I went out to a night club and when I went a little over my usually routinely "bedtime". Is this probably due to the stressful and energy demanding experience of going out : loud music, a lot of people, shouting ...? Maybe the little shift in me going to bed a little later and loosing 1 or 2 hours of sleep that I usually get from day to day? Anyone ever experience something similar?
